Host Lynn Poole reviews highlights of programs from the past year: "A Hospital Never Sleeps" (1/21/52) takes viewers behind the scenes at Johns Hopkins Hospital at night; "Artist and the Doctor" (12/17/51) reveals medical artists' work, including photographic art and "moulage" at the Department of Art as Applied to Medicine founded by Max Brodel in 1885 at the Johns Hopkins School of Medicine; "The World From 78 Miles Up" (9/11/51) shows film clips, diagrams, and explanation of the operation of the Navy's Aerobee rocket as it gathers atmospheric data; "Solar Power for Food and Fuel" (2/11/51) describes solar energy research and offers an explanation and microscopic view of plant cells engaged in photosynthesis; "Is It True?" (10/22/51) differentiates between the myths and facts about hypnosis; "It's a Fact" (12/3/51) demonstrates the facts of radiant heat using a Crooke's radiometer and explains Bernoulli's Principle; "Krilium for Tomorrow" (2/4/52) introduces Monsanto's soil conditioner for creating porous soil for better plant growth and uses time lapse photography to show plants' growth rate in the product.

Dr. Andrews compares the irregular molecules of water to the regular ones of ice and explains that ice floats because it is less dense than water. He then shows a diphenyl oxide molecule model and explains that it freezes at room temperature and sinks and is therefore used to remove impurities from a liquid. He demonstrates how skating on ice creates pressure causing ice to melt enough to allow gliding on water, which couldn't be done if the water froze at a lower temperature. Dr. Andrews points out that the molecules of iron in a drill and sodium chloride in salt are arranged in a regular pattern and are therefore "frozen." He then adds liquid nitrogen to water, alcohol, glycerin, and molasses to compare the differing results. Ways of measuring temperatures include household thermometers, Beckmann thermometers (accurate to 1000th degree), and electrical thermometers such as platinum resistance, thermocouple, and bolometer (measuring to the millionth of a degree).

Orthopedic surgeon Robinson describes three types of bones that break: ribs or skull, with which the underlying organs must be protected; facial bones, which require accurate, fine correction; and large, long bones, which must be held in place promptly and securely. Dr. Robinson shows x-rays of broken femurs and a diagram of how bone heals, explaining that the deformity must be corrected first and then held in place until a bridge of new bone is formed. A patient demonstrates the range of motion in his formerly fractured elbow that was held together with a metal plate and screws. Other x-rays display the intramedulary, a diamond-shaped stainless steel nail used to hold a femur fracture in place and allow weight bearing. A model of the hip joint and femur with surrounding muscles proves that without such a supportive rod, the muscles would override the bones and cause deformity or shorten the length of the leg. Dr. Southwick introduces former patient William Brown and explains how a metal rod was inserted.

Lynn Poole discusses some of the reasons for underwater research: studying alewife fish in Lake Hopatcong, NJ; researching predator fishes; harvesting agar from seaweed for iodine, ice cream gelling agents, and other uses; and obtaining magnesium from the sea. Cartoons illustrate historical diving gear and models show current masks, snorkels, and fins. Jacques Cousteau and Emile Gagnan developed the regulator and diving suit, which became synonymous with SCUBA (self-contained underwater breathing apparatus). Divers from Johns Hopkins's Chesapeake Bay Institute model both warm and cold weather diving gear, and Dr. Carritt, researcher at the institute, explains how an oceanographer uses SCUBA to investigate such underwater activities as the health of oyster beds. In a film clip, scientist-divers explore the Gulf of Mexico's bright oily crescent for Saucony-Vacuum and Magnolia Oil Companies. A diagram shows the anticline, fault, and stratigraphic oil traps of this region.

In this second program in a three-part series on peacetime uses of atomic energy, Lynn Poole demonstrates how radioactive iodine has been collected in a woman's thyroid for diagnosing goiter. An animated film shows the differences in size, shape, and stability of various atoms, the unstable ones being labelled radioactive isotopes. Dr. Bugher, of the Atomic Energy Commission, claims that the use of nuclear energy has advanced medicine by 25 years. For example, radioactive isotopes can be used to study the actual functioning and behavior of plants and animals, to trace and diagnose diseases such as thyroid problems, and to treat and cure diseases such as polycythemia, a form of cancer. He also demonstrates a thulium x-ray unit and narrates a short film showing cobalt-60 radiation of a patient with cancer. Gamma radiation is compact, reliable, and intense. Dr. Bugher notes that cesium, separated from the waste of atomic reactors, is a useful source of radiation. commercial electrical power. Dr. Hafstad, Director of the Reactor Development Division of AEC, discusses the costs and problems of harnessing atomic power. He points out that although our coal and oil supplies are dwindling and uranium supplies are vast, the cost of generating power from the atom is currently prohibitive. However, he predicts that, within the next five to fifteen years, as nuclear power is developed, its costs will fall.

Dr. Phelps explains that cerebral palsy is an injury to the portion of the brain dealing with the control of muscles for the arms, legs, and speech and generally does not affect one's intelligence. Because the parts of the brain affected (cortex, cerebellum, and basal ganglia) do not regenerate, surrounding brain cells must be trained to carry out the missing functions. This is done through physical therapy. Dr. Phelps describes the activities of therapists at the Children's Rehabilitation Institute working with children on reciprocal exercise patterns and training them on the stabilizer, crutches, and parallel bars. Mr. Schwartz works with children on blowing exercises, speech and auditory therapy, and speech training using a mirror. Children demonstrate other exercises including grasping and releasing blocks, placing pegs in holes as part of a game, practicing dressing skills on a doll, and typing on an electric typewriter. Dr. Phelps offers hope to the afflicted, giving the example of Betty Lou Driver who learned how to walk at the Institute and now as an adult works there, helping other children.

In this last program of the three-part series produced with the cooperation of the Atomic Energy Commission (AEC) on peacetime uses of atomic energy, Lynn Poole shows a model of the nation's first commercial nuclear reactor, the Shipping port power plant in Pennsylvania. He lists the products of this nuclear reactor as a result of splitting uranium-235: heat, fissionable materials, fission products, and atomic radiation. Dr. Manov, of the AEC, explains radioactive isotopes such as carbon-14 and why irons or other household appliances can not be atomic powered. He describes the ways radioisotopes can be used in industry for such purposes as checking metal castings for flaws, gauging thicknesses, measuring the wear and life of a cutting tool, tracing oil flow in pipelines, and applying the process of handling dangerous materials to other purposes. A film shows the application of radioisotope tracers to improve milk production in cows, eggshell thickness in chickens, and fertilizer use in plants.

In celebration of the 75th anniversary of Thomas Edison's invention of the electric light bulb, this program deals with the history of electricity and its current use in medicine. A film explores electricity's timeline: sparks created from rubbed amber, William Gilbert's study of magnetism, Benjamin Franklin's demonstration of lightening as electricity, Alessandro Volta's first electric battery, and Thomas Edison's 1879 incandescent electric light. Dr. McKusick explains the limitation of stethoscopes to show the need for spectral phonocardiography, a Bell Labs invention which records three-dimensional heart sounds. To create a spectral phonocardiogram, the doctor places a microphone over the patient's chest to record the heart's sounds on magnetic tape, but only the abnormalities are displayed in the final product. An EKG is also made simultaneously for comparison. Lynn Poole notes that research on guided missiles let to the next method of detecting heart disease, ballistocardiography, which is in its experimental stages.

Dr. Strieby, of American Telephone and Telegraph Co., demonstrates Bell Labs' recent invention of a solar battery, capable of producing sufficient electric voltage from any light source to operate a telephone. However, most telephone services have large power plants and storage batteries, which function when no light is available, so there is no reason to substitute a solar battery. Dr. Strieby next demonstrates a "personalized telephone" prototype ("like Dick Tracey's"), which functions like a mini-FM broadcasting station using transistors activated by a solar battery. This is only experimental and short-range because of the length of antenna required to transmit beyond a few hundred feet. Dr. Strieby then explains how a solar battery is built, using silicon from DuPont that is purified through a diagrammed process. Ultimately, with the addition of arsenic and boron gas, the thin sheets of silicon create a positive/negative juncture that allows light to become electricity.

Dr. Whitehorn briefly discusses the roles of the psychiatrist and the social worker and notes that the psychiatric clinic is like a lab of human nature. Dr. Frank, a psychiatrist, and Ms. Slaughter, a psychiatric social worker, then interact with actors to dramatize three actual cases: a family's conflict, an individual's depression, and an adolescent's problems. They conclude that the problems of living are common and solvable.
